Recent uses of connectedness in functional analysis
Biagio Ricceri
Perhaps, it is not too far from the truth to say that, among the great concepts (as compactness, completeness, order, convexity) on which functional analysis is based, connectednes…
Infinitely many local minima of sequentially weakly lower semicontinuous functionals
Biagio Ricceri
We give an overview of some applications of a general variational principle.
Some research perspectives in nonlinear functional analysis
Biagio Ricceri
The object of this lecture is to propose a series of conjectures and problems in different fields of analysis. They have been formulated with the aim of introducing some innovative…
Covering dimension and nonlinear equations
Biagio Ricceri
Theorem: Let X and Y be two Banach spaces, Phi: X to Y a continuous, linear, surjective operator, and Psi: X to Y a completely continuous operator with bounded range. Then, one has…
